Memcache::get -- memcache_get — Retrieve item from the server

### Beschreibung

Memcache::get(string `$key`, int `&$flags` = ?): string
Memcache::get(array `$keys`, array `&$flags` = ?): array
memcache_get(Memcache `$memcache`, string `$key`, int `&$flags` = ?): string
memcache_get(Memcache `$memcache`, array `$keys`, array `&$flags` = ?): array

Memcache::get() returns previously stored data of an item, if such `key` exists on the server at this moment.

You can pass array of keys to Memcache::get() to get array of values. The result array will contain only found key-value pairs.

### Parameter-Liste

`key`
  The key or array of keys to fetch.
`flags`
  If present, flags fetched along with the values will be written to this parameter. These flags are the same as the ones given to for example Memcache::set(). The lowest byte of the int is reserved for pecl/memcache internal usage (e.g. to indicate compression and serialization status).

### Rückgabewerte

Returns the value associated with the `key` or an array of found key-value pairs when `key` is an array. Returns `false` on failure, `key` is not found or `key` is an empty array.

### Beispiele

Beispiel #1 Memcache::get() example

`<?php
/* procedural API */
$memcache_obj = memcache_connect('memcache_host', 11211);
$var = memcache_get($memcache_obj, 'some_key');
/* OO API */
$memcache_obj = new Memcache;
$memcache_obj->connect('memcache_host', 11211);
$var = $memcache_obj->get('some_key');
/*
You also can use array of keys as a parameter.
If such item wasn't found at the server, the result
array simply will not include such key.
*/
/* procedural API */
$memcache_obj = memcache_connect('memcache_host', 11211);
$var = memcache_get($memcache_obj, Array('some_key', 'another_key'));
/* OO API */
$memcache_obj = new Memcache;
$memcache_obj->connect('memcache_host', 11211);
$var = $memcache_obj->get(Array('some_key', 'second_key'));
